When making new landspaces wwhat is the best way to go about it? Do you make the hills and valleys first then add the big things like cliffs and mountains or start with the items that define the terrain and blend the land into it? How do you get a natural looking distribution of trees, shrubs, rocks ect? Interior cells or even the area around buildings is easy because you just put in what you would expect of people living there but I have a really hard time with terrain and caves.
